In a study of parents' perceptions of their children's size, researchers asked parents to estimate their youngest child's height
maks197457 [2]

Answer:

B) TS = -6.51, p-value = 0.0000

Step-by-step explanation:

Sample size, n = 39

μ = 7.5 cm

Null hypothesis, H₀ = 7.5 cm

(I.e. Average height of youngest child is 7.5 cm)

Alternative hypothesis, H_{a}\neq  7.5 (The youngest child's age is underestimated by 7.5 cm)

Standard deviation, \sigma = 7.2 cm

In order to be able to reject the null hypothesis,

the formula for the test statistic:

t = \frac{- \mu}{s/\sqrt{n} }

t = \frac{- 7.5}{7.2/\sqrt{39} }

t = -6.51

P - value

P(x < 7.5) = P(z < -6.51)

Checking the p-value for z < -6.51 in the normal distribution table

P(z < -6.51) = 0.0000

p - value = 0.0000
